The simulation results suggest that force potentiation induced by Cav1.3 channel activation is strongly modulated not only by firing history of the motoneuron but also by length variation of the …

WebbThe reasoning is that slow motor units impede ballistic movements while exclusive recruitment of fast units would be optimal. However a recent study demonstrated that the recruitment of slow motor units does not pose any such problem ( Holt et al., 2014 ). Webb1 mars 2002 · Motor units were identified as slow if their twitch time to peak was >60 ms and fast if it was <50 ms. Further evidence of unit type was provided by their force-frequency relation using stimulation rates of 20, 30, 40, 50, and 80 pps.
